JOHN HENRY HUNTER, OF WEBB CITY, ARKANSAS.

CU LTIVATO R.

SPECIFICATION forming part of Letters Patent No. 470,574, dated March 8, 1892.. Application filed July 11, 1891. Serial No. 399,193. (No model.)

To all whom it may concern:

Be it known that I, JOHN HENRY HUNTER, a citizen of theUnited States, residing at lVebb City, in the county of Franklin and State of Arkansas, have invented certain new and useful Improvements in Cotton-Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved cotton-cultivator, in which the scraperbeam is so constructed and attached that it can be readily removed when desired, toconvert the cultivator into an ordinary doubler shovel plow, my invention being provided with means for adjusting the distances between the several beams or standards with.

The handles 3 are secured and braced to the beams 1 2, as shown.

4 indicates the removable scraper-beam, on

the lower rear end of which is mounted thescraping-blade 5. The forward end of this beam is curved in the same horizontal plane at nearly a right angle to the body of the beam and is then curved around to form an open loop or U-shaped end 6. The forward end of the straight part of the scraping-beam is formed wit the aperture 7, and the extremity of the curved end is formed with the aperture 8, the two apertures registering with each other, and a retaining-bolt 9 passes through these apertures.

To place the scraper attachment in its operative position, it is only necessary to remove the bolt 9 and slip the curved front end 6 of the scraper-beam over the forward portion of the main beam 1 and replace the rethe three beams.

taining-bolt 9 through the apertures 7 8. A threaded rod 10 passes through transverse apertures in the beams 1, 2, and4, and nuts 11 are fitted upon it, one pair on each side of It will now be seen that by turning these adjusting-nuts 11 the distance between the main beam and the auxiliary beam 2 and the distance between the scraper-beam and the beam 2 can be readily adjusted to the exact width required. The scraper-beam, as shown, is shorter than the beam 2 near which it is placed. The removable beam 4, as before stated, carries the scraping-blade.

A small plow-blade 2 is mounted on the middle beam 2, while at the rear of the beam 1 is mounted the blade 12, which is shown in the drawings in Fig. 3, and which I shall now describe. two narrow curved sections 12 12, which merge at their forward ends into a beveled and sharpened point. This blade is adjustably secured to the beam 1 by the clampingplates 13, so that it can be adjusted up or down, as desired, to regulate the depth of its out, and it will be seen that while this blade will cut readily through the ground its open character will enable the earth to pass through it between the two side sections of the blade, making a much cleaner out than is possible with the ordinary solid blade. By raising the blade 12 slightly the lower pointed end of the depending tooth 1, which is connected to the beam 1, will project down below the blade, so as to act as a subsoiler.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my new and improved cotton-cultivator will be readily understood. The scraperbeam can be readily removed when desired, leaving the plow arranged to'operate as a By closing the beams 1 and 2 together when the scraper-beam 4 has been removed and using only one blade the cultivator can be used as a one-horse scraper.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. As an improvement in cultivators, the combination, with the beams 1 and 2, carryrying their respective blades, of the remov- This blade 12 is formed of the ICO able beam 4, provided with the scraper-blade, formed with the angular U-shaped forward end having the opposite apertures 7 8, and provided with a removable rctaining-bolt 9, substantially as set forth.

2. In a cultivator, the combination, with a beam and a cutting-tooth connected to and depending from said beam, of the open blade comprising the converging sections merged into a point at their lower ends and straddling the lower portion of the tooth and a suitable means for adj ustably connecting said blade to the beam, substantially as and for the purpose set forth.

3. In a cultivator substantially as described, the combination, with the main beam, the

ward end to said main beam, and the removv able beam having the angular U-shaped loop at its forward end straddling the main beam and connected thereto, of the transverse threaded rod taking through the respective beams and nuts mounted on said rod on both sides of the said beams, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN HENRY HUNTER.
